GS4, the world's largest security company, will publish an interim statement on Monday.

The group, which operates in more than 100 countries, reported a pre-tax profit rise of 18 per cent, though margins were disappointing and investors will hope to see improvements in this update.

Barclays is due to announce its third quarter interim management statement on Tuesday. Nick Raynor, investment adviser at retail stockbroker The Share Centre, said: "It would be a huge surprise if Barclays were to come out with any fundraising plans from its shareholders, however we would not rule this out. "The news of the sale of its stake in the Qatari group, which initially helped Barclays emerge from the mire, should help stabilise the share price."

Hsbc is also due to publish its third quarter interim management statement.

Its £10billion rights issue was seen as enough to bolster its coffers, and it remains one of the few remaining banks offering yield, though there are some concerns with regards to its exposure in the Far East.

Vodafone is due to release its interim results the same day.

Rival Orange will be selling the iPhone prior to Christmas and Vodafone will not get this opportunity until the NewYear.

Sainsbury's will announce its interim results onWednesday.

Raynor predicts the results may well be insignificant as investors and analysts will be eager to see any further sign of a bid from the Qatar-based company.

He added: "Trading is expected to have improved, as all other supermarkets are showing better figures."

Scottish & Southern Energy will also publish its interims on Tuesday.

Wind power is a significant focus for SSE at the moment with several new projects being agreed upon and further sites in the pipeline.

Nuclear is also key to SSE's future with analysts believing this is the source of choice for the UK Government as power supplies start to come under pressure.
